Application filed. November I container may be in the form of a can with a cylindrical side wall, or in any polygonal i or curved form, but preferably in the form of a firkin with a taperingside wall, The paper stock of which the container isV constructed may be single ply or multiple ply with or without incorporating a binder.

rll`he paper stock used in the container yis, prior to formation, more or less porous, and therefore subject to expansionv and contraction due to varying temperature and humidity. I have found that under compression of from 6,000 to 10,000fpo'unds per square inch, the stock becomes highly compressed and practically `solidified so as to be substantially unchangeable in dimensions by moisture or heat. Also I have found that the portions of the stock folded under suoli pressure may, under certain conditions,

unite, cohere, become welded together or consolidate with each other along the meeting surfaces. For instance, if stock is used, which is practically non-calendered, the fibers at the meeting lsurfaces meet or interlace somewhat as they do in the structure ofthe paper stock itself, so that a practically integral vformation at these points is produced. This is true especially when the stock is made more pliable by heating, so that not only does the finished container re main substantially unaffected by Varying atmospheric conditions, and therefore maintains its 'gage dimensions, but the folded I portions resist separation along their meeting surfaces to an extent depending upon the texture of the stock, but 1n some cases as ,much as the body itself ofithe folded poi-tions. The use of asphaltum or adhesive material as a binder, heated by the dies or otherwise in forming the container, increases the (lcgreeof solidification even when the binder originally exists between the plies of the paper stock and not on either surface of the multiple-ply stock. lVhen semi-calendered 'stock is used without a binder, the meeting surfaces of thestock may be more readily separated by force. but with a binder a greater degree of resistance to separation is present. vlVhether or Vnot the folded portions are consolidated, or merely brought 7, 1919.

PAPER. CONTAINER. 'j

into intimate surface contact, I have found that as a result of the highly-compressed and practically-solidified lcondition of the folded portions resulting from the great pressure used in forming the container, and also as a result of the forms of construction hereinafter described, the container, and particularly the neck, bottom and closures thereof, take a rigid set impenetrable vto moisture and liquids, and permanently maintained at gage dimensions under normal atmospheric conditions.

Irrespective of the form of the container v and the bottom closure therefor, the invention comprehends as one of its parts a paper containerwith a reenforced neck, preferablyy double-reenforced, formed from a continuation of the stock of the side wall and folded undergreat pressure into rigidly set portions in intimate surface contact, which portions may or may not be united or consolidated depending principally upon the surface finish of the stock and Whether or not a binder is used. Preferably, the meeting edges of the side Wall and the folded neck portions are rigidly set in intimate surface Contact, with or Without being consolidated, and theneck has -a flat periphery without a joint so that the tendency to separate or `collect foreign matter at the junction of the side- Wall and neck is reduced in a container that is nicelyV finished In the specific embodiment hereinaftery iial portion enclosed Within the other portions,l the joining section of the base and intermediate portions-lying fiat over the periphery of the terminal portion, and the joining section of the intermediate and terminal portions-lying inv uninterrupted conformity with the inside face of the lside Wall. lVliere the neck has a cap-retaining groove, it -is advantageous to have the intermediate portion extend inside the container, because the upper and lowerperipheral edges of the groove are then better Aadapted to tightly' grip a cap seated therein, particularly where the upper peripheral edge thereof lies outside the lower peripheral edge to form an extended bearing surface against which the cap is tightly seated and prevented from en into the groove.

tering` the container further. lin that case, lt prefer further to flare the neck outwardly from the side wall, so that the cap is guided lfVhere the neck is reentorced and solidified to give a sutcient body of stock rigidly set, the cap is tightly retained in the groove although removal therefrom at will.

The invention comprehends as another el its parts a permanent closure at either or Vboth ends oit a paper container of any suitable form wherein a paper member may have a folded base portion with a. reversely-extending terminal portion of abbreviated length, the continuing portion oit the side wall el the container preferably being,I consolidated or rigidly set in intimate surface contact with the inside and outside surfaces et the base and terminal portions to form a hermetically-sealed interlocked joint. The closure may have a flat outer periphery on which to stand. ot a width totaling' a double thickness ot the member and a triple thick- -a can or irkin for transportingv and storing liquids or solids. Whereas the side wall is comparatively thin, and therefore economical of stock, the reenforced neck and the interlocked bottom closure furnish a sutliciently thick body of stock on which to work under the great pressure required to cause practical solidilication, or cohesion of the layers of the stock, whether of single or multiple ply with or without a binder, and to consolidate or rigidly set the folded portions in intimate surface contact maintaining their1 ,frage dimensions after forming, Thus, not only are the parts impenetrable to moisture, liquids and Solids, but when tapered they nest perfectly` and when capped after filling;` they invariably produce a tightly sealed container.

ln the accompanying drawings illustrating the preferred form of my invention in application, as an example, to containers having a tapering side wall with a permanently-sealed bottom-closure and a removable cap in a cap-retaining; groove of a multireeniiorced neck, wherein the folded portions of the bottom closure and neck are consolidated. v

Fig. 1 is an elevation, partly in section,

of a container of single-ply stock, with a fragment ot the cap in place; Fig. 2 is an enlarged detail ot the double-reentorced nec: thereof; 3 is an enlarged detail et the permanently-sealed bottom closure thereof; Fig, fr is au enlarged detail of the double reenter-ced neck :termed of two-ply stock incorporating a binder; and Fig". 5 is an enlarged detail of a pernianentiy-sealed bottom closure therefor termed et two-ply stock in the side wall and in the bottom, beth corporating a binder.

ln beth enibodimenls, the container has 'tal'iering side wall l of non-calendered stock.

a double-reentorced neck 2, and a perinanently sealed bottom closure 3, all circular in cross section.

Ret'errine' te the embodiment ot Figs. l, 2 and Il, the double-reenforced neck is formed ot' a base portion l continuing;- 'troni the side wall l, an intermediate portion 5 reversely extendingr inside the container, and a terminal portion (i enclosed between the other two portions, the base and intern'iediate portions having;l a joining section l with a llat periphery, and the joining,- section t3 between the intermediate and terminal portions lying` in smooth conformity with the inside surface ol the side wall. Vlhe neck has a cap-retaining` groove i) bounded below by the joining section 8 and bounded above by the upwardly Haring section lO having' an angle ot' taper greater than that of the side wall l. t paper cap ll, in the form olf a disc and of suitable stock, is retained in the groove 9.

l have found/that the great pressure which a multi-reenltorced neck of this kindis capable et withstanding in being formed by spinning or compression, is sufficient to consolidale the turned-over portions by forcing the fibers thereof into intimate meeting or interlacing,l and thereby produce such a solid formation as to rigidly set and retain the neck at gage dimensions, that is, at the dimensions at which it is origil'lally formed. Furthermore, the consolidation produced at 12, where the side wall l meets the joining section 8, precludes the entry ot moisture, liquids, or solids between the folded portions, whereas the consolidation produced between the section 7 and the periphery of the terminal portion (5 precludes capillary action tlnfough the paper .stock of the neck.

lt will be observed that the diameter oi the upper peripheral edge of the cap-retaining groove 9 is greater than that ot the lower peripheral edge, or lies outside it. Accordingly, not only does the cap 11 have an extended bearing' surface at 18, but, as a re- Sult et the resiliency of the neck 2, due in part to its multi-reenforcement ot consolidated portions and the resulting` retention ol" its gage dimensions` the cap, which inherently retains its diameter, is pressed so lll) lin

lll.

tightly along the upper peripheral edge of the groove that a tight seal is obtained be! tween the neck and'the cap.4 However, the cap may be removed at will by pulling up its center or prying between its periphery and the groove. Furthermore, the. aring section assists in guiding the cap into 'the groove 9, whereas the lesser diameter of the lower peripheral edge of the groove ordinarily prevents the cap from being forced further into the container.

The bottom closure ofthe container is formed .by interlocking the continuing portion ot' the side wall 1 ,with a bottom member 14 oflnon-,alendered stock. In this closure, the base portion 15 and the terminal portion 16 of the abbreviated length are cnclosed along their inside and outside surfaces b y the continuing portions 17, 18, 19 of the side wall, the closure having a flat outer periphery at 20 ot' a width totaling three thicknesses of the side wall and two thicknesses ot' the bottominember. A flat inner periphery at v21 -supports the bottom member 14 around the periphery thereof and acts to hold the bottom member at the side wall. The intermediate 'ledge 22 covers the periphery of the terminal portion'16, while the joining section 23 of the base and terminal portions of the bottom member covers the periphery of the downwardlyextending portion 19.

I have found that the great' pressure which an interlocked joint of this kind is capable of withstanding in being formed by spinning or compression, is suiiicient to con-l solidate the folded portions and to rigidly set and retain the bottom closure at gage dimensions. Furthermore, the impenetrability of the closure, and the solid formation thereof, serve to preserve a hermetical closure against the egress of the contents of the container and against the ingress of air,

moisture, liquids or solids from the outside. The closure is further enhanced by theconsohdation existing between the inner 'periphery at 21 and the bottom member 14,/

while the consolidation of the intermediate ledge 22 with the periphery of the terminal portion 1G, and the conxolidation between the joining section 23 with the periphery of the 'portion 19 preclude capillary action through l the paper stock of the inter-locked portions.

The embodiment shown in Figs. 4 and 5 is similar to that of the preceding embodiment excepting that the side wall is made of two-ply non-calendered paper stock 24,

` 25 incorporating a binder 26 of asphaltum or adhesive. Likewise the bottom member is paper of two-ply non-calendered stock27, 28 incorporating a binder 29 of asphaltum or adhesive. In applying pressure 'by dies, which are. preferably heated to about 200o F., the multi-reenforced neckand` the interlocked bottom closure are solidified to `a greater degree with the two-ply stock in-A seated in the groove 9, and more solidly compacting the bottom closure `in the interlocked joint. Furthermore, the folded portions of the neck and-bottom are consolidated to a greater degree.

lVhether of single-ply or multiple-ply stock, the container herein described is particularly suitable for nestin for transportation, the caps, of course, eing removed. The smooth inside and outside surfaces of the container between' the neck 2 and the bottom member 4, togetherl with the uninterrupted lconform-ity existing between the 1nsidesurface of the side wall 1 and the join ing section 8, assist materially in reducing the hazard of damage in nesting and separating' the containers, and increase the numi ber of containers capable of being nested in a given length'. The substantial permanency the herein described character of the formation, further improves this condition in practice.

Generally I I phite paper stock` no adhesive being used between the folded portions. The thickness ot' the stock depends upon the form and capacity of the container, the. number ofl plies used, and the quality of the paper stock. For sulphite paper stock used for containers with tapering side walls ot' one-pint capacity, thirty-point thickness for single-ply stock 'and lifteen-point thickness for two-ply stock are satisfactory. The proper thicknessuof the cap and the bottom member depends upon their diameter, and the material with which the container is tobe filled, al thickness ot' about sixty-point stock being satisfactory for a' single-ply cap, about` thirty-point stock for a single-ply bottom member and about iit'tccn-point stock for a two-ply bottoirrmember, in a container of one-pint capacity and ot" substantially the proportions illustrated in Fig. 1, when used for liquids.

Containers herein disclosed are suitable for transporting and storing liquids, as milk, molassesv` etc., or solids, as butter, lard, etc.

prefer to use long-fiber sul In certain cases, the finished containers are A parailined to render them completely waterproof, Vihether or not they are parafined,

they are comparatively strong 4and durable particularly the neck .and bottom, and they retain then' gage dimensions and hermetical closures almost permanently both before and after filling.
